Mid-Ohio Sports Car Course

Lexington, Ohio · 3.64 km · 2.26 mi · clockwise

Mid-Ohio Sports Car Course in Lexington, Ohio is modeled here on the Full Course with Chicane — the clockwise 15-turn layout that MotoAmerica and the venue's own motorcycle track days run — 3,641 m (2.26 mi) on the modeled centreline. Turn 5 is a flat-out kink the reference line runs straight through. Elsewhere the simulated profile splits sharply: Turns 1, 2 and 12 (Thunder Valley) hold minimums of 129–171 km/h (80–106 mph), while Turns 4, 7 and 8 drop to 74–75 km/h (46–47 mph). Heaviest braking is into Turn 6 off the back straight: 210 m on a liter bike. Simulated lap estimates: 1:33.4 for a liter bike (138.6 km/h / 86 mph average), 1:34.7 for a Supersport 600, 1:37.6 for a 650 twin. All figures are physics-simulation estimates.

  • Slowest corner (simulated): Turn 7, 74 km/h (46 mph) minimum on a 35.9 m radius
  • Longest simulated brake zone: 210 m into Turn 6 on a liter bike (162 m Supersport 600, 114 m twin)
  • Biggest elevation changes: 5.4 m (18 ft) drop through the Keyhole, 4.4 m (14 ft) climb through Turn 13
  • Longest single corners: Turn 1 at 210 m and the Keyhole at 171 m of arc

Turn 1 is the longest corner in the model at 210 m of arc: a left on a 110 m effective radius that climbs 3.7 m (12 ft) away from the start-finish straight. The simulation brakes 75 m out on a Supersport 600, 99 m on a liter bike and 48 m on a 650 twin, arriving at turn-in at about 148 km/h (92 mph) and holding a 129 km/h (80 mph) minimum through the long arc. The exit builds to 158 km/h (98 mph) on the fours and 155 km/h (96 mph) on the twin, one of the higher exit speeds on the circuit, straight into the chicane.

The Keyhole is a 171 m right on a 37.4 m effective radius that falls 5.4 m (18 ft), the largest descent on the circuit. The simulation brakes 57 m out on the fours and only 15 m on the twin, reaching turn-in at just 83 km/h (52 mph) and a 75 km/h (47 mph) minimum, within 2 km/h of the lap's slowest point. The exit is where the corner matters: 139 km/h (86 mph) on the Supersport 600 and liter bike, 134 km/h (83 mph) on the twin, launching the line onto the back straight and through the flat-out Turn 5 kink toward the highest speeds of the lap.

Turn 6 hosts the heaviest braking on the circuit. At the end of the back straight the model starts slowing 210 m before the corner on a liter bike, 162 m on a Supersport 600 and 114 m on a 650 twin, so that all three classes reach the turn-in at 120 km/h (75 mph). The corner itself is a 126 m right on a 54.9 m effective radius, dropping 3.2 m (10 ft), with a 91 km/h (57 mph) minimum and an exit of 115 km/h (72 mph) — 114 km/h (71 mph) for the twin — into the tight Turn 7 that follows.
